there's still no avr-libc support equivalent to boot.h for the xmega chips, right?
And the new "xtiny" and "mega 0" chips have similar boot/spm usage?
Is there a different set of standard wrapper functions for SPM on these chips, or is everyone rolling their own? :-(
(I did find various freaks discussions with sample xmega bootloader code, dating back to 2009... That's 10 years ago!)
